DEFECTS
SOLUTIONS
Pilot arcing difficult
- Check the type, pressure and flowrate of pilot gas according to the
scales.
- Check that there is sparking of the H.F between the electrode and
the nozzle.
- Check the gas conduit over the entire circuit: to do this, place a
blocked nozzle on the torch and carry out a gas test : Check that the
pressure displayed at the pressure-reducing valve does not move
after having closed the gas cylinder ;
if the pressure drops
leak.
Spark-extinction at the time of transfer
- Reduce the power run-up time-delay.
- Check the cutting gas pressures.
NOTE :
Be careful of the pressure increase of the pressure-
reducing valves ; be careful not to move the torch
too far away at the time of the transfer: risk of arc
breaking.
Difficult transfer
- Check the connection of the electric wire running to the part
(ground wire).
- Check the electrode circuit, especially the connections to the
bundle connections.
- Check the condition of the cone nozzle : it is to be changed if the
cutting channel is splayed downwards.
